Abstract

La présente invention concerne un procédé de détermination d'au moins deux résistances équivalentes d'isolement pour un système électrique intégrant une source électrique (2), un onduleur (11), une charge électrique (3), et un circuit de mesure (5). Les mesures sont réalisées en fonctionnement du système électrique, lorsque les interrupteurs commandés de l'onduleur (11) sont dans une séquence nulle. La présente invention concerne également un système de commande mettant en œuvre un tel procédé.The present invention relates to a method for determining at least two equivalent insulation resistances for an electrical system integrating an electrical source (2), an inverter (11), an electrical load (3), and a measurement circuit (5 ). The measurements are carried out during operation of the electrical system, when the controlled switches of the inverter (11) are in a zero sequence. The present invention also relates to a control system implementing such a method.
